Title: Improvements relating to power transmission gearing
IPC: H02K7/116
Filed: 1956-11-22
Abstract: 794,957. Variable-speed gearing. GENERAL ELECTRIC CO. Nov. 22, 1956 [Nov. 22, 1955], No. 35785/56. Class 80 (2). A gear mechanism, particularly suitable for a washing-machine, for driving a shaft 61 at either of two different speeds in the same direction by reversing the direction of rotation of a driving shaft 22 comprises a pinion 30 rotatably mounted upon an eccentric 24 on the driving shaft 22 of a reversible electric motor 12 and in mesh with an internally toothed gear 40. A one-way clutch device 26, 33, 31 (see also Fig. 3) is provided between the eccentric 24. and the pinion 30 and a one-way brake device 41, 42 (see also Fig. 2) is provided between the internal gear 40 and the gear casing 21. A plate 32 secured to the pinion 30 is coupled for rotation to a disc 60 on the driven shaft 61 through pins 50, 62 sliding in radial slots 52, 64 of an intermediate disc 53 to allow of the eccentric movement of the pinion. When the shaft 22 is rotated in one direction the one-way clutch 26, 33, 31 is inoperative and the pinion 30 rolls around the internal gear 40 which is held from rotation under reaction torque by the brake 41, 42. A reduced rotation is imparted to the pinion 30 in the opposite direction and this rotation is transmitted through the coupling 32, 53, 60 to the shaft 61. If the direction of rotation of the driving shaft 22 is reversed the one-way clutch 26, 33, 31 operates to clutch the pinion 30 to the shaft 22 and eccentric 24. The shaft 22 then drives shaft 61 with a direct drive in the same direction as before, the internal gear 40 being allowed to rotate freely by the brake device 41, 42.

Title: Method of producing monokaryotic mycelia of coriolus versicolor
IPC: C12P21/00
Filed: 1977-08-25
Abstract: If a dikaryotic mycelium of Coriolus versicolor (Fr.) Quél., a fungal species of the genus Coriolus of the Polyporaceae, is subjected to mechanical treatment by grinding or shearing in a liquid medium, and the mycelium treated in this way is subsequently or simultaneously cultured in submerged culture, a monokaryotic mycelium is produced which differs from the dikaryotic mycelium in morphological and physiological respects. The monokaryotic mycelium obtained in this way is a novel product and characterised by its extremely high growth rate in comparison to the known dikaryotic mycelium. The material obtained by extraction from cultures of the noval mycelium moreover has an outstanding physiological activity.

Title: Governor
IPC: B61H13/00
Filed: 1972-07-07
Abstract: 1358857 Valves; fluid pressure brakes COAL INDUSTRY (PATENTS) Ltd 7 July 1972 [30 July 1971] 35909/71 Headings F2V and F2F A fluid-pressure governor has a spring-loaded valve member 34 in a bore of a shaft 20 moved off its seat, when a housing 8 rotates about the shaft above a predetermined speed, so as to vent a fluid pressure inlet 28 via apertures in a housing end plate 10. Rotation of the housing causes balls 60 to move radially outwards under centrifugal force to cause a rotor 46 and an actuating member 40 to move axially against springs (64) and move the ball 34 off its seat. The fluid flow path is via an aperture 56 in rotor 46 and short cylinder 12 on the end plate so that the fluid pressure venting acts on a portion 48 of the rotor 46 which for a short time slides as a piston in the cylinder 12 to urge it in a direction to unseat the ball 34. The governor 1 is used in a brake circuit of a mine car having spring-applied fluid pressure-released brakes 69. When line 70 is disconnected from a fluid pressure reservoir on decoupling the mine car from a haulage vehicle and it is required to move the mine car, manually-operated pump 94 is actuated to release the brakes 69, close off line 70 with valve 72 and move piston 88 to pivot the housing of the governor 1 into contact with a wheel 108. Thus at a predetermined speed the brakes 69 are applied. When the reservoir is reconnected to line 70 pilot valve 106 vents the cylinder 84 to allow the housing of the governor to pivot away from the wheel.

Title: Automatic control systems for synchronising an electric oscillator to a train of pulses
IPC: G01S1/24
Filed: 1960-10-21
Abstract: 890,038. Automatic frequency and phase control systems; radio navigation. SPERRY RAND CORPORATION. Oct. 21, 1960 [Nov. 25, 1959], No. 36174/60. Classes 40(5) and 40(7). In the system of Specification 721,108 as applied to a LORAN receiver with automatic gain control, the operation of the skywave indicator, which shows when synchronisation of the local oscillator has been effected incorrectly with the sky-wave signals rather than with the ground wave signals, may be upset, e.g. when the sky-wave signal amplitude is substantially the greater. This upsetting effect is minimized according to the present invention by adjusting the sensitivity of the sky-wave indicator according to the average noise level in the receiver. Received LORAN pulses are amplified at 2 and detected at 4, the detector output pulses, Fig. 2, (A) being differentiated at 5 to produce pulses, Fig. 2, (B) having a zero crossover point 28. These pulse points are synchronized with locally generated pulses, Fig. 2 (C), on line 9, derived from a sinusoidal oscillator 16 via a phaseshifter 15, shaper 18 and delay network 20, by a sampling gate (phase detector) 10, the output of which via a filter 11 and amplifier 12 controls a servomotor 13 which adjusts. the phase shifter 15 in the corrective sense. Coarse adjustment of the phase shifter may be effected manually at 35 by observing a sync-indicator 30 actuated by the filtered output of a further sampling gate 6 which compares the phase of the locally generated pulses on line 9 directly with the output pulses of detector 4. The received LORAN signals may show both a ground wave signal 31 and a skywave signal 32, Fig. 2(D), at the detector output, giving zero cross-over points 33, 34, Fig. 2(E), with either of which the local pulses on line 9 may be synchronized. Normally, synchronization with the ground wave is required, improper synchronization of the local pulses on line 9, Fig. 2(F), with the skywave being indicated on a sky-wave indicator 24, which is actuated by comparing the earlier occurring local pulses, Fig. 2(G), at point 19 with the ground wave signal 31 in a sampling gate 7, the D.C. output of which actuates the skywave indicator via a threshold gate 22. The sync indicator input is fed as an automatic gain control voltage over line 3 to the R.F. amplifier 2, and to prevent false actuation of the skywave indicator by random bursts of high level noise, a D.C. potential, proportional to the average value of the noise signal at the detector 4 output, and derived therefrom via a band-pass filter 8, detector 25 and filter 27, is fed over line 23 as threshold control voltage. Thus upon a reduction of receiver noise as as result of reduced receiver gain, the threshold level of gate 22 is correspondingly reduced so that the diminished amplitude of the ground wave signal 31 as sampled by gate 7 will be sufficient to actuate the skywave indicator 24.

Title: Improvements in fluid spring
IPC: B60G17/052
Filed: 1955-12-28
Abstract: 773,069. Road-vehicle spring-suspensions; pneumatic springs. UNITED STATES RUBBER CO. Dec. 28, 1955 [March 21, 1955], No. 37101/55. Classes 108(2) and 108(3). A fluid spring comprises a flexible diaphragm 26 connected between a cylinder 24 and a piston 25, and formed of a flexible fabric coated with a fluid impermeable composition, the individual cords of the fabric being relatively inextensible and laid so that the individual cords extend between the cylinder 24 and the piston 25 with approximately one half of the cords extending across the remaining cords at an angle of between 30 degrees and 150 degrees. As shown, applied to a road vehicle independent front suspension, of the wish-bone-link type, the piston 25 is connected to the lower wish-bonelink 30. The cylinder 24 is integral with a transverse chassis-frame member 27. The hollow interior of the frame member 27 forms a fluid chamber 28. The diaphragm 26 before assembly, Fig. 7, is cup shaped with an opening at the bottom of the cup where it is adapted to be secured to the piston 25. This opening is surrounded by a bead 38 formed from a bundle of wires embedded in the fabric. A similar bead 37 is formed at the other end of the diaphragm. The bead 38 may be secured to the piston by means of a recessed cover plate 40 bolted to the piston, Fig. 2. Alternatively, Fig. 11, the piston may be formed with an annular recess 42 of slightly greater diameter than the diameter of the opening in the diaphragm, and comprising a tapered flange portion 43. A corresponding face formed on the diaphragm for engaging the face 43 has a series of ribs 47. In a further alternative, Fig. 10 (not shown), the arrangement is similar to Fig. 11, but an undercut recess formed in the surface 43 is engaged by a corresponding annular projection of the diaphragm 26. The fluid impermeable composition may be natural or synthetic rubber or plastic material. The fabric of the diaphragm 26 may be of weftless, or weakened weft, cord fabric, or may be of braided material. The cords of the fabric may be of nylon, cotton, rayon, steel, or glass. The diaphragm may be secured to the cylinder in the same way as it is secured to the piston. Similar fluid springs are used to support the combined rear axle and differential unit, Figs. 8, 9 (not shown). The axle is prevented from lateral movement by means of a panhard rod, and fore-and-aft movement is controlled by means of longitudinal links. In this construction, also, the hollow interior of a transverse frame member forms an air chamber 28. The chamber 28 of each spring is connected through a respective regulator valve to a fluid supply tank common to the four springs of the vehicle, Fig. 1 (not shown). The opposed annular surfaces of the cylinder 24 and piston 25 may be non-parallel. This results in the area acted on by the fluid varying according to the position of the piston 25 relative to the cylinder 24. The cylinder 24 may not necessarily be of cylindrical cross section but may be of oval or elliptical shape.
